Abstract :
In this paper the design of the analog baseband chain for UWB receivers in a standard 90 nm CMOS technology is presented. The baseband chain is composed by the 5th order elliptic analog low-pass filter and a programmable gain amplifier (with up to 60 dB gain). Due to the large UWB signal bandwidth (250 MHz), the design has been carried-out using a MATLAB model taking into account the capacitance parasitics effect and the opamp finite bandwidth impact on the filter transfer function. From a single 1.2 V supply voltage, the total power consumption is 13 mA per channel, the in-band and out-of-band IIP3 is 20 dBm and the maximum IRN for G>15 dB is 9 nV/radicHz.
